FRANCIS T. SMYIHE, OF ST. LOUIS, MISSOURI.

FLOATING WATER-ELEVATOR.

SPECIFICATION forming part of Letters Patent No.y 320,184, dated June 16,1885.

(No model.)

To all whom it may concern.-

Be it known that I, FRANCIS T. Snr'rnic, a citizen of the United States, residing at St. Louis, in the county of Louis and State of Missouri, have invented a new and useful Ilnprovement in Floating \Vater- Elevators, of which the following` is a specification, reference being had to the accompanying drawings.

My invention relates to an improvement in floating water-ele\v'ators; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure I is a side elevation of a machine embodying my invention. Fig. 2 is a top plan view of the same.

My invention is particularly designed to irrigate lands adjacent to water-courses.

c represents a pair of twin floats, which are arranged parallel to each other, and secured at a suitable distance apart by the beams l) c. The inner side of the front end of each ofthe lioats is made angular, as at d, so as to direct the current of the stream in which the floats are moored between said Heats, and thereby secure increased strength of the cur' rent at this point.

d represents a shaft that is journaled in bearings e, and extends from one fioat to the other at a suitable distance above the lioats, as shown. An under-shot water-wheel,f, is fixed to the shaft d', and is rotated by the current of the stream.

lo the ends of the shaftd are xed large spur-wheels g, that mesh with pinions z,which are fixed to the shafts i. The shafts z' are journaled in movable blocks la, that allow a slight play of the inner ends of the shafts fi, and levers Z are pivoted to the tloats and connected to the shafts. By moving the levers back or forth the shafts can be moved so as to cause the pinions h to mesh with the gearwheel g or to be disengaged therefrom.

To the outer ends of the shafts t' are secured crank-wheels m.

Pumps a are secured to the outer sides of the floats, and the plunger-rods of these pumps are connected to the crank-wheels by connecting-rods o. As the paddle-wheel is revolved by the action ofthe current,the pumps are worked thereby, and the water raised from the stream by the pumps can be conveyed by suitable pipes to any desired point. Thepumps n are ordinary force or lift pumps.

At p, I show a chain-pump, which may be employed, if preferred. In this instance a chain-wheel, m, is substituted for one of the crank-wheels m, and the endless chain ofthe pump is moved by the wheel m', as shown.

A floating watelelevator thus constructed is adapted to be operated by the current of a stream, and will be found very valuable for irrigating purposes.

Having thus described claim- 1. rIhe twin floats u., arranged parallel to each other and secured together, in combination with the water-wheel journaled between the tioats, the gear-wheel g, liXed to the shaft ofthe water-wheel, the shafts ,swiveled loosely at one end in blocks attached to the lioats, the movable blocks L' on the other ends of the shafts, pinions lL on the latter meshing with the gear g, levers l, pivoted to the tioats and my invention, I

connected to the shafts t', and the pumps corrnected to the latter, as set forth.

2. The Iioats a, arranged parallel to each other-,and secured at a suitable dist-ance apart by the beams b o, the inner side of the front end of each float being set at an angle, d, to the outer side, in combination with the shaft d', journaled in bearings of the floats,a waterwheel mountedon the shaft, gear-wheels g, fixed on the ends of the shaft d, the shafts swiveled loosely at one end in blocks att-ached to the floats, the movable blocks L on the other ends of the shafts, guides for said blocks to move in, pinions h, mounted on the shafts and adapted to mesh with the'v gear y. levers Z, pivoted to the fioats and connected to the shafts t', and the pumps connected to the latter, for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signa-ture in presence of two witnesses.
